Abnormalities in spermatogenesis are closely related to disruptions of glucose and lipid metabolism in Sertoli cells. The metabolic environment of Sertoli cells is hypoxic, with glycolysis and fatty acid β-oxidation being the primary metabolic pathways. In Sertoli cells, glycolysis produces lactate to provide energy for spermatogenic cells, while fatty acid β-oxidation generates ATP. However, the relationship of glucose and lipid metabolism with spermatogenic cell development in Sertoli cells, and the interplay between glucose and lipid metabolism remain unclear. Various hormones, including sex hormones, can affect glucose metabolism of Sertoli cells by endocrine regulation. The activation or inhibition of signaling pathways such as AMPK, mTOR, and Akt can alter the expression levels of glycolysis-related transporter genes and the generation of fatty acids, thereby affecting the glycolipid metabolism in Sertoli cells. Some transcription factors such as PPARγ can regulate downstream fatty acid metabolism-related genes by directly binding to response elements, and can promote the oxidation of fatty acids in Sertoli cells. In this article we elaborate on the key factors influencing glucose and lipid metabolism in Sertoli cells and their interconnections, and their potential clinical implications, offering new insights for the precise targeted treatments of male infertility.</p>","PeriodicalId":24007,"journal":{"name":"Zhejiang da xue xue bao.

The primary endpoint was 2-year all-cause mortality. A MVACI prediction model was constructed based on the mortality risk factors identified by univariate and multivariate Cox regression analysis. Restricted cubic spline curves were plotted to assess the relationship between MVACI scores and 2-year all-cause mortality. The optimal threshold, determined by the maximum Youden index from receiver operator characteristic (ROC) curve analysis, was used to stratify patients. Kaplan-Meier method was used to calculate 2-year all-cause mortality and compared using the Log-rank test. Univariate and multivariate Cox proportional hazards models were employed to calculate hazard ratios (HR) and 95% confidence intervals (CI), evaluating the association between MVACI scores and mortality. Paired ROC curves were used to compare the discriminative ability of MVACI scores with the European System for Cardiac Operative Risk Evaluation Ⅱ(EuroSCORE Ⅱ) or the age-adjusted Charlson comorbidity index (ACCI) in predicting 2-year clinical outcomes, while calibration curves assessed the calibration of these models.
